Simple Linear Regression - Gradient Descent | NerdML

Simple Linear Regression using Gradient Descent - This video will help you to understand that Simple linear regression can be solved by Gradient Descent as well . I have tried to cover all aspects including inner functionality of this algorithm using gradient descent, mathematics derivations used behind this & coded a snippet.
Below topics are explained in this video:
1. Introduction? ( 00:06 )
2. Cost Function ( 00:33 )
3. Gradient Descent mathematical explanation ( 01:40 )
4. Finding the derivative of a Cost function using gradient descent (02:43)
5. Mathematical calculation on the actual dataset (06:38)
6. Coded snippet for finding best fit line using gradient descent (07:50)
